Question

If $R subset of A cross times B$ and $S subset of B cross times C$ be relations, then $open parentheses S o R close parentheses to the power of negative 1 end exponent equals$

(a) $S^{- 1} o R^{- 1}$
$R^{- 1} o S^{- 1}$
$S o R$
$R o S$

The correct answer is: (a) $S to the power of negative 1 end exponent o blank R to the power of negative 1 end exponent$
